Yowza, this thread does grow quick.
Many different conversations going on in this thread.
Well, different types of eyes could be developing in different ways simultaneously, and would all have evolved for roughly the same amount of time, at different rates. And there isn't necessarily anything that would prevent two separate species from developing similar traits independent of any relation. I would have to check out the fossil record for types of eyes from the earliest simplest to the earliest complex.
Here is a good source of information. It is the article that I was talking about when I mentioned the 1/2 million years for evolving eyes.
The available fossil record illustrates that the Cambrian explosion spawned the simultaneous birth of the principal invertebrate compound eye and the vertebrate camera-style eye. These eyes usually are just visible as dark imprints with no detailed structures preserved. This report on the compound eyes of Cindarella, showing the large size of ommatidial lens facets (60140 μm, Fig. 1b, c) and a large number of ommatidia (over 2000), indicates that it had extraordinary vision similar to that of living forms. Although we cannot know exactly how much organization in cellular function or morphology occurred in the Cambrian, this extraordinary visual surface confirms the occurrence of highly developed vision in the early Cambrian. Compound eyes seem to have evolved much more rapidly than other eye-types, from eyespots to complicated, advanced eyes, especially in arthropods. A monophyletic origin of the metazoan eye is strongly supported since Pax6 is involved in eye development in all bilaterian phyla33. If the metazoan eye is indeed monophyletic, then the time required for a simple eye to evolve within these different eye-types might be remarkably short. This hypothesis has been tested using a conceptual model involving a linear series of eyes, arranged from simple to complex, and as mathematically predicted by Nilsson and Pelger34, a patch of light-sensitive epithelial tissue could evolve by natural selection into a camera eye within only about 364 000 generations, in other words in less than half a million years. Thus compound eyes show the quickest rate of evolution during the early stages of eye evolution as the fossil record shows that evolution of the eye into a highly advanced compound eye was amazingly rapid22, 30, 35, 36, 37. The fossil record also indicates that image-forming eyes possessing a high resolution image probably evolved first in the arthropods due to the numerous ommatidia. In most phyla, although simple photoreception is almost universally present, no visional eyes evolved, although eyes evolved later in Annelida, Onychophora, Mollusca, and Chordata.

I will note as well there have been other scientists that disagree that it would only take 364,000 generations.
For my part, I would discuss my views regarding behavior, why I held them, and why I felt they were superior. I would set goals based on those views and then evaluate what the best way to achieve them would be. Others would be invited to share their views as well. We debate and convince and compromise until the objectively best solutions are determined.
Discuss it with whom? Unless, there was some meeting where all people on earth came together and evaluated behavior and determined what was superior we have no way to convey your views or views of others into working solutions that create an objective or universal shared view.
Creatures living in groups would be aware that cooperation is something that can help them, on some level. That would be part of their awareness of what is required for their own survival. They aren't necessarily consciously thinking long-term, multi-generational species survival. But their behavior will be steered towards that by survival pressures, like any other trait.
I think you agree that the most pressing and crucial trait is the self preservation trait and that would counter act any self sacrifice that one would take. It is counter to the whole system of survival as the main drive of selection. IF someone sacrifices themselves, they leave their family without a man to fend for them. The whole selfish gene thing is in my opinion the greatest argument against evolved morality.
Hold on, we don't know that about neanderthals. Just because not every individual thinks specifically in terms of far-reaching genetic survival of the species as a whole, doesn't mean creatures don't value others of their own species on some level. It doesn't even need to be a conscious thought.
That is easy to say today in our era. We don't have to worry about food, we just go to the market. We make money enough to help those less fortunate. To use our human experiences as a model for those in the past is faulty. Food had to be hunted for and gathered. Food was not always abundant and the sick or dying would hinder the prospect of moving quickly to keep up with herds of their food source. Self preservation would not be as simple and survival could depend on whether you were strong and able to provide for yourself and your family. If you were to put your health or body in jeopardy you were risking the well being of your family as well.
I think humans do have a general set of behaviors across the board. There are anomalies as you would expect, but by and large there are shared values - family, aversion to killing, etc. You posted a set of 10 Commandments earlier in this thread and pointed out how humans generally keep to the ones that aren't specifically related to worshiping the christian God - killing, lying, stealing, cheating are all things that create strife and instability, and it makes sense for creatures like us to dislike them. To me, that speaks more to these shared behaviors being natural traits rather than supernaturally imbued. If they are supernatural, it would suggest God cares more about people getting along than He does about what they think of Him, or whether they think of Him at all.
Creatures like us are not like the creatures of the past. When looking back do we see that there would be some trait that could bring about the concept that stealing was wrong? I mean yes, we see chimps punishing one of their own for stealing food, but punishment is our definition and they could have simply got angry at the one stealing the food and acted upon the anger. Punishment would have to be seen as we see it for this to be true and we don't know if it is in this case. The anger punishes the wrong doer but does it persuade the wrong doer that what they have done is wrong, or does it make the wrong doer more careful not to be caught next time? Did the other members that were showing their anger do so because they believed it wrong to steal food and that they themselves would not steal food, or were they just acting out their anger on the one that got caught. We can not assign our own definitions and motivations on creatures that can not communicate their own motivations for doing what they do. We tend to anthropomorphize.
Do you believe miracles are undetectable? That suspensions of natural law have no impact in the world?
I don't believe that all supernatural actions are miracles. Some are and some are just actions that are either executed by or guided by the power of God or the "super" natural aspects of Him. A level higher than natural. However, the point is that anything that we would find in nature would be considered nature. So if something doesn't fit within a theory it is an anomaly of said theory.
Dunno - same way God created Himself?
Within the Christian worldview God is not a Created being. He is an eternal being. Yep, and you are right I don't know what that entails.
Universal laws by definition could only be violated supernaturally.
We see this even in Newton's Law of Universal Gravitation and Einstein's Law of Relativity. So we explain those things that are anomalies naturalistically even if they do not "fit" into the laws perfectly. So there would be nothing that you could point to, just as it is now that you can not say is outside of the natural world.
Fair enough. I've no reason to assume the supernatural is involved at any level, but I'll remain open to the possibility that it is.
Ok.
Magic, supernatural, specially created, divinely forged, etc. Don't believe in it. I think stuff can be great without it.
You do believe that, however your belief if I am correct is wrong. You can accept that things are just the way even if they appear designed but that is your choice. You have to accept something that appears to be more than a chance circumstance or coincidence, something that gives every indication that it was designed to be just the way it is as something that just so happened to be the way it happened. That goes counter to your usual standard of assessing your world from what I gather from our conversations.
Do you think that if any of these parameters were off, God could not have created life, or kept the universe from collapsing, etc?
I think God could do what God wanted to do and this is what God wanted to do.
There are certainly gaps in human knowledge. Lightning was once attributed to various gods, disease to demons. If I'd lived in a time where those misconceptions were widely accepted as truth, would I be correct in doing the same? Wouldn't it be more honest to admit I don't know the cause rather than accepting an incorrect explanation? An all-powerful deity makes a very convenient explanation for anything we don't understand, but is it the correct one?
It isn't that we don't understand it, we do. It is that as a naturalistic worldview, it is not acceptable to allow the supernatural in our explanations. We know the parameters are such that life could not have formed as we know it on earth. We know that if such a small change as the weight of a grain of sand was present or absent from the materials in creating the universe it would have collapsed upon itself or never formed at all. We understand that is a fact. It is how we explain that finding that is at issue.
Fair enough. I would modify it to 'the supernatural is not evidently required'.
Ok, but I find that is dismissing what we know to remain consistent within your own worldview. You have to dismiss that there is no law of physics that can explain the fine tuning of our universe.
Question - are any of these precise measurements you've brought up the reason you became convinced of God's existence?
This is one piece of evidence that gives a lot of support to the existence of God. It is just one piece among multitudes of evidence for me.
But does faith take precedence over reason and evidence? Should it ever?
Reason no, evidence perhaps. Evidence changes with new evidence at times.
I've heard people claim both. Neither one seems like it would warrant it, personally.
Warrant what?
Free will is an aspect of intelligence, which I believe evolved. If you're going to hit me with the 'if we evolved naturally free will is an illusion because it's constrained by our biology' argument, I'll head that one off right now by pointing out that free will is necessarily constrained by reality whatever its origin happens to be - we can't 'will' ourselves to do certain things, but this doesn't mean free will doesn't exist.
You believe intelligence evolved but you don't have evidence that shows it, you believe that free will exists even though are brains are hard wired to think the way they think? I'm somewhat confused here.
Gonna cover the last bit in 2nd post, since its a lot of questions.
OK thanks.
